This　study　models　previously　unknown　domestic　geographical　transfers　of　toxic　substances　in　waste　electrical　and　electronic　equipment　(WEEE)　by　using　the　minimum　distance　and　maximum　flow　(MDMF)　algorithm.　Using　lead　scrap　as　a　typical　case,　the　results　present　a　complete　picture　of　domestic　geographical　transfers　in　China:　(1)　the　total　interprovincial　transfer　of　lead　scrap　is　996　k　tonnes,　accounting　for　63%　of　total　lead　recycled;　(2)　lead　scrap　transfers　between　4　pairs　of　provinces　are　more　than　100　k　tonnes　with　an　average　distance　perk　tonne　of　lead　scrap　transferred　of　967　km;　and　(3)　using　outdated　processing　technology,　national　pollutant　emissions　of　lead,　CO2　and　SO2　resulting　from　these　transfers　can　reach　50,　497,　and　105　k　tonnes,　respectively.　In　addition,　if　provinces　recycle　locally　generated　and　imported　LAB　at　a　ratio　below　1:1,　or　50%　imported　LAB,　using　the　advanced　process,　emissions　can　be　reduced.　The　domestic　geographical　transfer　model　has　the　following　advantages:　(1)　it　is　helpful　for　the　geographic　distribution　and　capacity　planning　of　WEEE　recycling　plants;　and　(2)　it　provides　a　method　that　may　be　less　time-consuming　in　estimating　the　external　quantified　environmental　responsibility　of　the　WEEE　generating　provinces.　(C)　2018　Elsevier　Ltd.　All　rights　reserved.
